also inhibits the appearance of Fmθ The purpose of this experiment is to investigate the effect of Fmθ biofeedback (BF) training upon the appearance of Fmθactivity, compared with both intact control (CN) and autogenic training (AT) groups. Twenty-four university students (all females) were served as subjects. They were assigned into one of three groups, i.e., group-AT, -BF, and -CN. Six of 8 subjects in each group were rich in Fmθ activity in the preliminary experiment. In the group-BF, auditory BF training was performed 5 times within 2 weeks. In group-AT, the standard exercise of AT. Was run within the same period. In group-CN, no treatment was run for 2 weeks. We compared the Fmθ activity in the pre- and post- training sessions (Test-1 and Test-2, two weeks apart). In each test session subjects performed continuous adding task with modified Uchida-Kraepelin Test Sheet for five min without any other treatment, I.e., without BF in group-BF. Only in the group-BF the mean duration of Fmθ bursts increased from Test-1 to Test-2. Additionally, in the group-BF, the mean appearance time of Fmθ per 3-min increased between pre- and post-BF non-feedback control sessions in the last two training days. Such effects were almost statistically significant (p<.10). Mean eyeblink rate in the group-BF decreased both from Test-1 to Test-2 and from pre- to post-BF non-feedback control sessions in all training days. State anxiety scores (STAI-I) also significantly decreased from Test-1 to Test-2 in all groups. In the group-BF, the score of STAI for each training day did not changed from pre- to post-sessions. All subjects in the group-BF reported they could acquire the awareness of Fmθ appearance as a result of biofeedback training of Fmθ. But only one subject reported she could control the appearance of Fmθ voluntarily. The results suggest that it will be possible for all subjects to control the appearance of Fmθ with its biofeedback training, if the training would be lasted more. It is expected that the biofeedback training of Fmθ would be effective to relaxation and to concentration in mental activity.
